If you have access to regular climbing either indoors and outdoors I would personally say no, it wil probably leave you with chronic tendon overuse injuries. At this stage you will probably be fine with a pullup bar, and learning climbing movement by getting climbing on as wide a variety of rock and indoors as much asd possible.

For normal pull up routines its a good idea to have a hangboard of sorts, or even dead hangs(with slightly bent elbows ) on slopers, but do stay away from the smaller crimps or 3 and 2 finger holds until you climb grade 25 comfortably - that advice given to me way back by Justin Hawkins, he was crushing HARD at that time!

Warm up and down regularly, stretch, and you'll be ok if you stay on the big stuff...

Stay away from fingerboards until you're climbing at least grade 25... Once you're confident on 25, then you can look into "advanced training" that is associated with fingerboards. You want to prevent yourself from getting injured, not invite injury at the beginning of your climbing career

I hate this real world place... I'd be more than happy to live out there rather...
